Definitions

  • the present invention relates to a fishing rod with a pre-inserted fishing line guide member which includes an enlarged diameter cylindrical portion capable of reducing the resistance of a fishing line when the fishing line is played out and drawn in through the fishing rod during a fishing operation.
  • a fishing rod with a pre-inserted fishing line guide member which includes an enlarged diameter cylindrical portion capable of reducing the resistance of a fishing line when the fishing line is played out and drawn in through the leading end of the fishing rod during a fishing operation.
  • the 5-3737 publication discloses a structure in which a fishing rod includes an opening formed in the leading end portion thereof and which opening is enlarged in the leading end direction.
  • An enlarged diameter cylindrical member, uniform in the circumferential direction thereof, and made of ceramics is mounted on the inner surface of the leading end portion thereof.
  • the structure disclosed in the present 5-3737 publication prevents the fishing line from being in contact with the steep or sharp corner portion of the rod structure and, therefore, this structure can reduce the damage of the fishing line in this sense.
  • the behavior and contact of the fishing line is widely distributed in the leading end portion of a fishing rod. That is, since tension is applied to the fishing line and the speed of the fishing line varies when it is played out and drawn in, as shown in FIG. 6, the fishing line behaves in a meandering manner in the enlarged diameter cylindrical portion of the leading end portion of the fishing rod.
  • the behavior range of the fishing line does not coincide with the shape of the enlarged diameter cylindrical portion and, during the fishing operation, the fishing line can be contacted strongly and widely with the inner surface of the enlarged diameter cylindrical portion of the rod or with the ceramics ring, which increases the resistance of the fishing line.
  • a fishing rod with a pre-inserted fishing line guide member in which the whole periphery of the inner surface of a fishing line guide cylinder mounted on the leading end portion of a rod pipe is enlarged in diameter more greatly than the inner peripheral contour of the rod pipe leading end portion when it is extended in the direction of the axis of the rod pipe.
  • the lower inner surface of the fishing line guide cylinder is downwardly shifted and enlarged in diameter with respect to the above axis more greatly than the size of the upwardly enlarged diameter of the upper inner surface of the fishing line guide cylinder.
  • a wear resisting guide member having a curved inner peripheral surface is provided at least in the leading end portion of the lower inner surface of the fishing line guide cylinder.
  • a fishing rod with a pre-inserted fishing line guide member in which the fishing guide cylinder has a transverse section shape which is long lengthwise, that is, small in the right-and-left or horizontal width thereof and proportionately large in the vertical dimension thereof.
  • a fishing rod with a pre-inserted fishing line guide member in which the fishing line guide cylinder is mounted on the rod pipe leading end portion in such a manner that it can be freely rotated about the axis of the rod pipe.
  • the fishing line guide cylinder When the fishing line guide cylinder is formed larger in diameter than the inner periphery of the rod pipe leading end portion, then the contact of the fishing line with the inner surface of the fishing line guide cylinder and with the guide member is decreased and weakened in the leading end portion of the fishing rod when the fishing line is played out and drawn in during the fishing operation, thereby being able to reduce the resistance of the fishing line. Also, in general, in the behavior of the fishing line during the fishing operation, when the fishing line is played out, in particular, during the latter range of the playing-out behavior, or when the fishing line is drawn in, the fishing line will be strongly contacted with the guide member inner periphery of the lower portion of the fishing line guide cylinder.
  • the lower inner surface of the fishing line guide cylinder is downwardly shifted and enlarged in diameter much more greatly than the size of the upwardly enlarged diameter of the upper inner surface of the fishing line guide cylinder, the resistance of the fishing line due to its strong contact with the guide member inner periphery can be reduced to a great extent.
  • the width of the fishing line guide cylinder in the right and left direction can be set smaller than the width in the vertical direction thereof.
  • the upper portion of the fishing line guide cylinder need not be so enlarged in diameter as the lower portion thereof, the upper portion can be set rather small. That is, although the leading end portion of the fishing rod is heavy in weight from the viewpoint of the operation of the fishing rod, because the unnecessary width of the fishing line guide cylinder in the right and left direction as well as the size of the upper portion thereof can be reduced in this manner, the leading end portion of the fishing line guide cylinder can be reduced in size and weight.
  • the fishing line guide cylinder when the fishing line guide cylinder is mounted on the leading end portion of the rod pipe in such a manner that it can be freely rotated about the axis of the rod pipe, regardless of whether the fishing rod is used in its normal state or upside down.
  • the fishing line guide cylinder can be rotated such that the lower inner surface thereof can be always situated at the bottom and thus the fishing rod is stabilized due to the gravity with respect to the fishing line guide cylinder as well as due to the pulling action of the fishing line caused by the weight of a bait. This facilitates the fishing operation of the fishing rod.
  • a second wear reducing and fishing line friction reducing member associated with the line guide is inserted so as to abut directly against or near the end portion of the fishing rod end pipe. In this way, fishing line wear and friction is even further reduced from using the fishing line guide alone.
  • the fishing line guide of the present invention can be easily replaced on the end section of a given fishing rod pipe.
  • the fishing line guide can be selected to best suite a fishing style or condition.

  • FIG. 1 is a side view of a first embodiment of a fishing rod with a pre-inserted fishing line guide member according to the invention.
  • a rod pipe is one of a type that a front rod 10 is connected to a base rod 12.
  • a reel seat 14 is mounted on the base rod and a reel 16 is fixed to the reel seat 14.
  • a fishing line guide portion 12A is formed at an appropriate position in the base rod 12.
  • a fishing line 18, which is drawn out from the reel 16 is passed through the fishing line guide portion 12A and further through the front rod 10 and is drawn externally from a fishing line guide cylinder 16 mounted on the leading end portion of the front rod 10.
  • the front rod 10 and base rod 12 are connected to each other.
  • marks 20A and 20B for specifying directions are given on the connecting portions of the respective rod pipes.
  • rod pipe means the front rod 10 hereinafter.
  • FIG. 2 is an enlarged longitudinal section view of the leading end portion of the fishing rod.
  • FIG. 3 is a front view of the fishing rod leading end portion when viewed from the direction of an arrow C shown in FIG. 2.
  • the rear portion of the fishing line guide cylinder 16 is fixed to the rod pipe 10.
  • the fishing line guide cylinder includes a bugle-like main body which is situated in front of the rod pipe 10 and the whole periphery of the inner surface of the fishing line guide cylinder main body is enlarged in diameter more greatly than the inner periphery 10A of the rod pipe 10 when it is extended in the direction of the axis L of the rod pipe 10.
  • the lower inner surface 16D of the fishing line guide cylinder 16 is downwardly shifted and enlarged in diameter with respect to the axis L more greatly than the upper inner surface 16U. This relationship remains unchanged even when a wear resisting ceramics guide member 22 is mounted on the leading end portion of the inner surface of the fishing line guide cylinder 16.
  • the guide member 22 includes an inner peripheral surface 22S which is formed in such a curved surface as shown in FIG. 1, in order to prevent the fishing line 18 from being damaged even when the fishing line 18 is contacted with and is slid along the inner peripheral surface 22S as well as in order to be able to reduce the sliding resistance of the fishing line 18.
  • the inner peripheral surface of the leading end portion of the rod pipe 10 is formed in a chamfered surface 10C.
  • the fishing line When the fishing line is played out, due to the casting operation, the weight of a bait and the like, the fishing line is drawn out forwardly, obliquely and downwardly. That is, like a curved line L1 through a small diameter hole (inner periphery) in the leading end portion of the rod pipe.
  • the shape of the curved line L1 varies according to the tension to be applied to the fishing line, the speed of the fishing line, the rigidity (class) of the fishing line and the like, and the fishing line can be drawn out like a curved line L2. For example, in the latter range of the fishing line casting operation, the speed of the fishing line goes down so that the fishing line behavior varies from the state of the curved line L1 to the state of the curved line L2.
  • the fishing line when the fishing line is drawn in, the fishing line is drawn against the rod pipe linearly like a curved line L3 while it is in contact with the guide member 32.
  • the tension applied to the fishing line is small or when the speed of the fishing line is fast, the fishing line will be drawn against the rod pipe in such a manner that it is curved slightly upwardly as shown by the curved line L2.
  • the fishing line is played out and drawn in such that mostly it meanders vertically within the fishing line guide cylinder.
  • the upper inner surface of the fishing line guide cylinder is so formed as to include a space approximate to the shape of the curved line L1 that is the largest in the meandering curved lines of the fishing line, then the fishing line is in little contact with the inner surface and, therefore, the resistance of the fishing line during the fishing operation is reduced accordingly.
  • the speed of the fishing line goes down when it is drawn in or cast, then the fishing line is contacted with the inner peripheral surface of the guide member 32 as shown by the curved lines L2 and L3.
  • the fishing line is contacted along the curved surface of the guide member 32 between points 32P and 32Q in front of the linear portion and is thus changed in its direction before it is released externally.
  • the included angle formed between the linear portion of the fishing line guide cylinder 36 and the external curved portion at the front and rear end points of the contact area of the fishing line with the guide member is large. Therefore, the sliding resistance of the fishing line is large.
  • the curved line L3 turns out to be a curved line L3' shown by a two-dot chained line, so that the distance between the two end points 32P' and 32Q' of the contact area with the guide member is shorter than the end points 32P and 32Q of the above-mentioned contact area. That is, the angle to be formed between the linear portion of the fishing line guide cylinder in the rear of the contact area and the curved portion existing externally of the fishing line guide cylinder just in front of the contact area is reduced to a considerable extent as shown in FIG. 6. Therefore, the sliding resistance of the fishing line can be reduced to a great extent.
  • the reason why the width of the fishing line guide cylinder 16 in the right and left direction thereof is smaller than the vertical width thereof as shown in FIG. 3 is that, as described before, the fishing line meanders mainly in the vertical direction and does little in the right and left direction. To set smaller the width of the fishing line guide cylinder in the right and left direction contributes to the reduction of the size and weight of the leading end portion of the fishing rod.
  • the width of the upper portion of the fishing line guide cylinder can be set smaller than that of the lower portion thereof, which can contribute to the reduction of the size and weight of the fishing rod leading end portion.
  • the fishing rod including such a light leading end portion is improved in the operation thereof.
  • a fishing line guide cylinder 16' including a lower inner surface 16D' which is downwardly shifted and enlarged in diameter with respect to the axis L of the fishing rod more greatly than the upper inner surface 16U'.
  • a ceramic guide member 22' is mounted on the lower portion of the leading end portion of the inner surface of the fishing line guide cylinder 16'.
  • the guide member 22' includes an inner peripheral surface 22S' which is formed as a curved surface so as to allow the fishing line 18 to slide smoothly on the inner peripheral surface 22S'.
  • the fishing line guide cylinder 16' includes a rear portion 16A' which is fitted over a recessed portion 24A formed in a hold member 24, and the hold member 24 is in turn securely fixed to the leading end portion of the rod pipe 10.
  • the fishing line guide cylinder 16' is free to rotate around the recessed portion 24A and, therefore, it is also free to rotate about the axis L of the fishing rod 10.
  • the fishing line guide cylinder 16' is structured such that it can be freely rotated, then the lower inner surface 16D' of the fishing line guide cylinder 16' can be always situated at the bottom and is stabilized by itself due to the pulling action of the fishing line 18 caused by the gravity and the weight of a bait.
  • the resistance of the fishing line during the fishing operation can be reduced.
  • a guide member 26 formed of ceramics and having a circular section is mounted on the leading end of the hold member 24. And, since the fishing line 18 is guided in contact with the guide member 26 and the above-mentioned guide member 22' and not in contact with other portions of the fishing line guide cylinder, the resistance of the fishing line can be even further reduced.
  • FIG. 5 instead of the guide member 22' there is shown a guide roller 22" of ceramics by a two-dot chained line, which guide roller 22" is mounted rotatably with respect to the fishing line guide cylinder 16'. If the guide roller 22" is used, then the sliding resistance of the fishing line 18 can be further reduced.
  • FIG. 7 is a modification of the first embodiment shown in FIG. 2.
  • the fishing line guide cylinder 16 has a second wear resisting ceramic guide member 26 in the form of a ring for guiding the fishing line 18.
  • the first guide member 22 and the second guide member 26 cooperatively define a path for the fishing line 18.
  • the second wear resisting member 26 is fixed onto an internal surface of the guide cylinder 16 and is brought in abutment with a longitudinal terminus of the rod pipe 10. Further, a distance between the longitudinal axis L and an inner curved surface of the guide member 26 is set larger than a distance between the longitudinal axis L and an inner circumference of the rod pipe 10. It is, therefore possible to more surely prevent any destructive contact of the fishline 18 with an edge on the terminus of the rod pipe 10.
  • the first wear resisting member 22 and the second wear resisting member 26 cooperatively define a path for the fishing line 18 such that the path is enlarged toward a leading end of the guide cylinder 16 from the terminus of the rod pipe 10.
  • a third wear resisting member may be further arranged on the guide cylinder 16 between the first and second wear resisting member 22 and 26 as long as the third wear resisting member meets with a requirement that a minimum distance between the longitudinal axis and the inner peripheral surface of the third wear resisting member is smaller than a minimum distance between the longitudinal axis and an inner peripheral surface of a wear resisting member located further from the terminus than the third wear resisting member.
  • FIG. 8 is a modification of the second embodiment shown in FIG. 4.
  • a male thread 24 B is formed on an outer circumference of the holding member 24, and a female thread 16B is formed on an inner circumference of the guide cylinder 16', so that the guide cylinder 16' can be detachably mounted on rod pipe 10 through the hold member 16'.
  • a through-hole 16H is formed through the guide cylinder 16' at the lower inner surface 16D thereof so as to discharge water accumulated behind the guide member 22'.
  • FIG. 9 is also a modification of the second embodiment shown in FIG. 4.
  • This embodiment also has a feature that the guide cylinder 16' is detachable from the rod pipe 10. Instead of the formation of the male and female threads, this embodiment utilizes an engagement between a claw 16C and recess 24C. More specifically, two longitudinal slits (not shown) are formed in an upper portion of the guide cylinder 16' so that an elastically deformable arm having a claw 16C is defined between the slits.
  • the holder member 24 is formed with a recess 24C adapted to engage with the claw 16C.
  • FIG. 10 shows a feature that an angler can select one from among a set of different type guide cylinders in accordance with a given fishing condition or fishing style.
  • the upper one in FIG. 10 has a configuration similar to the second embodiment, the lower one has a configuration similar to the first embodiment, and the middle one has a configuration similar to a guide cylinder shown in FIG. 6 wherein circular cross-sections of the enlarged diameter cylindrical portion are concentric over to the leading end portion thereof with respect to the longitudinal axis L passing through the rod pipe 10.
  • the fishing line guide cylinder is formed such that the diameter thereof is greater than the diameter of the inner periphery of the rod pipe leading end portion, then it is possible to reduce the area and force of the contact of the fishing line against the inner surface of the fishing line guide cylinder and with the guide member when the fishing line is played out or drawn in during the fishing operation, so that the resistance of the fishing line can be reduced. Also, generally, in the behavior of the fishing line during the fishing operation, the fishing line is contacted with some force against the inner periphery of the guide member mounted on the lower portion of the fishing line guide cylinder.
  • the contact resistance of the fishing line can be greatly reduced. That is, the fishing line can be smoothly played out or drawn in, with the fishing line resistance reduced. Also, this makes it possible to reduce the size and weight of the leading end portion of the fishing rod with a pre-inserted fishing line guide member.
